UFC President Dana White today announced the change in plans. Rua (22-9 MMA, 6-7 UFC) originally was scheduled to face Manuwa (14-1 MMA, 3-1 UFC) in the headliner of next month’s UFC Fight Night 56.

Saint Preux (16-6 MMA, 4-1 UFC), meanwhile, was scheduled to fight Francimar Barroso (16-4 MMA, 1-1 UFC) in the event’s co-headliner, but Barroso is now being utilized as a backup in case of any further injuries, a UFC official confirmed with MMAjunkie. Barroso will likely be paid his show money whether or not he fights.
